The distribution of behavior over a heirarchy of actors is accomplished quite naturally in ROOM. This is described simply in the ROOM book (Selic, Gullekson, and Ward) in sections 6.5 `Heirarchical Structures' and 6.6 `The Linkage Between Structure and Behavior'. Container actors can have behavior defined for them, as can the actors that they contain. The behavior of both contained and container actors can cooperate, via a binding between an internal port on the container and an external port on the contained actor, to produce a combined action. It is rarely good design practice to force all behavior to occur in the actors at the lowest containment level.
